Muri iki gihe abantu bagenda barushaho kumenya ibidukikije, uruhu rw’ibidukikije hamwe n’uruhu rwa bio ni ibikoresho bibiri bikunze kuvugwa n’abantu, bifatwa nkibishobora gusimburwa n’uruhu gakondo. Ariko, ninde nyawe“uruhu rwatsi”? Ibi biradusaba gusesengura duhereye kubintu byinshi.
Eco-uruhu mubisanzwe izina ryahawe inzira yimpu. Ari mubikorwa byo gukora uruhu, mukugabanya ikoreshwa ryimiti, ukoresheje irangi ryangiza ibidukikije ninyongeramusaruro hamwe nubundi buryo bwo kugabanya kwanduza ibidukikije kwangiza uruhu. Ibicuruzwa by’uruhu rw’ibidukikije bikiri uruhu rw’inyamaswa, bityo rero mu kugura ibikoresho fatizo, biracyarimo ubworozi bw’amatungo no kubaga hamwe n’andi masano, kuva kuri uru rwego, ntabwo byakuyeho umusaruro w’uruhu gakondo w’ibibazo biterwa n’amatungo.
Mubikorwa byo kubyaza umusaruro, nubwo uruhu rwibidukikije rugabanya imyuka yangiza, inzira yo gutwika ubwayo iracyafite ibibazo by ibidukikije. Kurugero, uburyo bwo gutwika bushobora gukoresha ibyuma biremereye nka chromium, bishobora kwanduza ubutaka namazi niba bidakozwe neza. Byongeye kandi, imyuka ya karubone no kugaburira ibiryo by'inyamanswa mugihe cyo guhinga ntibishobora kwirengagizwa.
Ku rundi ruhande, uruhu rushingiye ku binyabuzima, ni ibintu bimeze nk'uruhu bikozwe muri biomass y'ibimera cyangwa izindi nkomoko zitari inyamaswa, binyuze muri fermentation, gukuramo, synthesis hamwe nibindi bikorwa. Ibikoresho bisanzwe bikomoka ku ruhu ni ibikoresho by'ibabi by'inanasi, ibihumyo mycelium, igishishwa cya pome n'ibindi. Ibi bikoresho fatizo bikungahaye ku isoko kandi birashobora kuvugururwa, birinda kwangiza inyamaswa, kandi bifite inyungu zigaragara z’ibidukikije duhereye ku gushaka ibikoresho fatizo.
Mubikorwa byo kubyaza umusaruro, gahunda yo kubyara uruhu rushingiye kuri bio nayo iratera imbere kugirango igabanye gukoresha ingufu no kugabanya imyanda. Kurugero, uburyo bumwe na bumwe bwo gukora uruhu bushingiye ku ruhu bukoresha ibikoresho bitangiza ibidukikije nka polyurethane ishingiye ku mazi, bigabanya imyuka y’ibinyabuzima bihindagurika. Byongeye kandi, kubera ibiranga ibikoresho byayo bibisi, uruhu rushingiye kuri bio narwo rufite imikorere idasanzwe mubintu bimwe. Kurugero, inanasi yamababi yinanasi nkibikoresho fatizo byuruhu rwa bio bifite umwuka mwiza kandi byoroshye.
Ariko, uruhu rushingiye kuri bio ntabwo rutunganye. Kubijyanye no kuramba, uruhu rushingiye kuri bio rushobora kuba munsi yuruhu rwinyamanswa gakondo hamwe nuruhu rwiza cyane rwibidukikije. Imiterere ya fibre cyangwa ibintu bifatika bishobora kuganisha kubushobozi bwayo bwo kurwanya kwambara biri munsi gato, mugihe cyo gukoresha igihe kirekire cyangwa gukoresha imbaraga nyinshi, byoroshye kwambara, guturika nibindi.
Urebye ku isoko, uruhu rw’ibidukikije ubu rukoreshwa cyane mu murima w’ibicuruzwa byo mu rwego rwo hejuru, nk'inkweto zo mu rwego rwo hejuru zo mu ruhu, imifuka y'uruhu n'ibindi. Abaguzi bamenya impamvu nyamukuru yacyo ni uko igumana imiterere n'imikorere y'uruhu ku rugero runaka, icyarimwe ikerekana igitekerezo cya“ibidukikije”nayo ijyanye nigice cyo kurengera ibidukikije imitekerereze yabantu. Ariko kubera inkomoko y’ibikomoka ku matungo, bimwe bikomoka ku bimera ndetse no kurinda inyamaswa ntibyemera.
Uruhu rushingiye kuri bio rukoreshwa cyane cyane mubisabwa biramba ntabwo ari ibintu byerekana imyambarire ihanitse, nka zimwe mu nkweto zerekana imideli, ibikapu hamwe n’ibicuruzwa by’uruhu. Igiciro cyacyo ni gito, kandi ibintu bitandukanye byibanze biva mubicuruzwa bitanga umwanya uhanga. Hamwe niterambere ryiterambere ryikoranabuhanga, umurima wo gukoresha uruhu rushingiye kuri bio nawo uragenda waguka.
Muri rusange, uruhu rwibidukikije hamwe nimpu zishingiye kuri bio zifite ibyiza byazo nibitagenda neza. Uruhu rw’ibidukikije rwegereye uruhu gakondo mu bijyanye n’imiterere n’imikorere, ariko hari impaka zo gukoresha umutungo w’inyamaswa ndetse n’ingaruka ku bidukikije; bio-ishingiye ku ruhu iruta iyindi mibereho irambye hamwe n’ibipimo bimwe na bimwe byo kurengera ibidukikije, ariko bigomba kurushaho kunozwa mu bijyanye no kuramba hamwe n’ibindi. Byombi mubyerekezo byiterambere ryangiza ibidukikije, ejo hazaza hazaba impamo“uruhu rwatsi”yiganje, bitewe niterambere ryikoranabuhanga, ibyifuzo byabaguzi hamwe ninganda zinganda kugirango turusheho gutera imbere.
